The tragic death of David Bowie may be dominating headlines but Donald Trump is up to his old tricks in the US.

The Republican Democratic presidential candidate has praised Kim Jong-un his form hand with his executed uncle.

Days after North Korea's latest nuclear test, Republican front-runner says North Korean dictator "doesn't play games"

During a Republican political rally in Iowa at the weekend, he repeated his assertion that Muslims should not be allowed to enter the US before turning his attention to the North Korean despot, who has carried out frequent purges of officials.

“You’ve got to give him credit. How many young guys - he was like 26 or 25 when his father died - take over these tough generals, and all of a sudden... he goes in, he takes over, he’s the boss,” said Mr Trump, known for his own less than subtle style of leadership in the American version of The Apprentice.

“It’s incredible. He wiped out the uncle, he wiped out this one, that one. This guy doesn’t play games.”

Mexico began the process of extraditing drug lord Joaquin "El Chapo" Guzman to the US, two days after the fugitive was recaptured following a dramatic, months-long hunt featuring film stars, sewer escapes and bloody shoot-outs.

Officials warned the process could take a long time as Guzman's lawyers file legal appeals and manoeuvre to keep their client in Mexico, where he has already escaped from maximum security prisons twice.

On Sunday, agents formally notified Guzman that he was wanted in the United States.

The attorney general's office said Mexican agents assigned to the international police agency Interpol served two arrest warrants to the drug lord, who is being held at the Altiplano prison following his capture by Mexican marines on Friday.

A controversial critical edition of Adolf Hitler’s Mein Kampf has sold out instantly after going on sale in German bookshops for the first time in 70 years.

Demand for the 2,000-page annotated version of the inflammatory text that hit bookstores on January 8 massively exceeded supply, with 15,000 advance orders for an initial print run of just 4,000 copies.

One copy of the edition, which costs £43 (59 euros), was even reportedly put up for resale on Amazon.de for £7,521.43 (9,999.99 euros).

The new edition of the notorious partly-autobiographical manifesto only appeared after the copyright, held by the German state of Bavaria which had refused to publish the book, expired on January 1.
